To provide a power steering device for an industrial vehicle improved in operability of a steering wheel.

In this power steering device for the industrial vehicle, oil pressure is supplied from a steering valve 6 controlled to be switched by the steering wheel 1 to a steering cylinder 8, dirigible road wheel 9 is steered by the steering cylinder 8, and the steering amount of the dirigible road wheel 9 is fed back to the steering valve 6 through a link 10 and a sector shaft 12. The sector shaft 12 is provided with a reaction force supporting means 16 for supporting the reaction force of a compression spring 6d generated when the steering valve 6 is switched, whereby the reaction force of the compression spring 6d is not transmitted to the link 10, and the influence of flexure and clearance of the link 10 is not exerted, so that the responsiveness of the steering valve 6 is improved so as to improve operability of the steering wheel 1.
